Part 15 (dome) has been cut out. It needs the upper part to curled around something round to become the petals for the dome.

Here is my glue setup and the tools I use. I squirt a good amount of glue on a piece of cardboard then use the stirring stick to apply and spread it onto parts. On the first paper model I attempted, I applied it straight from the bottle. That made the parts too wet. The used knife blade is for tight spots.

And here is part 9 (small parapet) finally glued in place. I had to trim both the end of the top and the bottom a bit. I really had trouble with this part as when you cut it out, it was quite hard for my fingers (which don't work so well after my mini-stroke of 2013) to fold right as it is quite flimsy.

I started on part 5. This is an important part as it joins two external walls and their artwork together. Only tab 5a is glued here as it is the tab that holds part 1 and 5 together.

The instructions say to do one part at a time so this will take a while.

I should mention two tools that help reach internal tabs. One is wooden coffee stirring sticks. They are great for getting glue and spreading it in hard to reach spots. Another are a pair of cross-action tweezers. These are great for squeezing parts together in hard to reach spots.

While dry fitting the parts, I noticed something wrong with Part 4. It took some careful viewing of Figure 3 in the book to find out what was wrong. In parts 1, 2, and 3, you bent the tabs towards the un-printed side. On part 4, only tab 4a gets bent in the direction; all other tabs get bent toward the printed side. Now that this has been corrected, I can start gluing parts 1-4 to the floor and each other.

Well, with the first cut, the first mistake. Make sure you don't have the rest of the parts stacked with the page you are cutting on.

Also make sure you don't use corrugated cardboard as a cutting mat. Your cuts can go off course when you cut through the first layer and into the corrugation.

Of course the damage was to the next part to use: Part #1, the front of The Library. I thought of using tape, but instead will glue a piece of scrap paper (from one of the pages) across the damage on the inside.

5 pages of parts for The Library. I think I will try good old Elmer's White Glue on this. I also have an Elmer's Glue Stick and will try that also. I will have to see if any of the stores around here have Loctite 401 glue. I saw some at Staples today but forgot to write down the number. I might also try the nearby Ace Hardware that just opened up.
